I wrote out a structured plan for my next big project. I couldn't have done that while drinking. It was great to be re-focused and going after my passion once again. I will be at the helm of this project so it'll be great to see it come to fruition under my sober guidance.
I also got a serious workout in at the gym and have re-dedicated myself to the health & fitness lifestyle (but I still hate cardio).
Whole different world.
